The following is the introductory knowledge of piano music theory that I have compiled for you. I hope it will be useful to you! Introductory teaching video of piano music theory knowledge. Basic piano music theory knowledge

1. Basic tone levels:

In the music system, the seven tone levels with independent names are called basic tone levels. These 7 scales are the sounds produced by the white keys on the piano today.

The names of basic sound levels are marked in two ways: note name and singing name. The note name of each note level is marked with letters. The roll call is represented by pronunciation. (As for the relationship between note names and roll call, we will explain it in detail in the mode and tonality section later.) Take C major as an example: the note names of the basic note level of C major are marked from low to high: C, D, E, F, G, A, B and their corresponding roll calls are do, re, mi, fa, sol, la and si.

In the music system, the marks of the seven basic tone levels (note names and roll calls) are used cyclically. That is, after C, D, E, F, G, A, B, it goes back to c, d, e, f, g, a, b or after do, re, mi, fa, so l, la, si, it is still do, re, mi, fa, sol, la, si? And so on. 2 ]9 p: M# Q `5 Q However, the pitch levels in each cycle are different, that is to say, although the note name (or roll call) is the same, the pitch is different. When labeling sound names, use uppercase or lowercase letters, or add subscripts after capital letters and superscripts after lowercase letters to distinguish them. For example: C, a, a1 (the following number? 1? should be in superscript form), B3 (the number? 3? should be in subscript form). The relationship between two adjacent tones with the same name is called "octave".

2. Changes in pitch levels:

Among the seven basic pitch levels, in addition to E and F (the keys of C are sung as mi and fa), B and C (the keys of C are sung as mi and fa), In addition to the roll names si and do), there is also a sound between two adjacent sound levels, which can be clearly distinguished by the human ear. 7 O) B u' \0 ^3 H: Z2 \. `/ Z4 a

Let us give an example? Between the C sound and the D sound, you can also get a pitch that is different from both C and D. It is different from the sound of D, which means that this sound is higher than the C sound but lower than the D sound. We can think that this sound is obtained by raising the C sound or lowering the D sound. This kind of sound obtained by raising or lowering the basic sound is called a change of pitch. The changing pitch level is reflected on the piano as the sound produced by the black keys. Changes in pitch are marked by adding # (sharp) or b (flat) in front of the basic pitch. For example, the sound between the C sound and the D sound, we can say that it is obtained by raising the C sound, so we mark it as #C (pronounced? C sharp?), at the same time, we can also think of it as It is obtained by lowering the D sound, so it can also be marked as bD (pronounced as ?D flat?).

It can be seen that #C and bD are actually the same sound, but they are marked in different ways. This kind of sound with different marking methods and the same actual pitch is called "enharmony". 9 ]/ ?) kamp; q* s! b; B2 B3 |

3. Grouping of sounds:

As we mentioned before, the seven basic tones in the musical sound system Names are recycled. Therefore, there will be many sounds with the same sound name but different pitches. In order to distinguish them, we divide the sound sequence into many "groups".

/ n# Z; b/ Z) a, u5 o* @2 p: f The central group is called "Small Character 1 Group", which is represented by lowercase letters and the number 1 in the upper right corner, such as c1, d1, e1 , f1? (The numbers after the letters should be in the form of superscripts, the same below) The sound groups higher than the small character group 1 are named as ?small character group 2?,?small character group 3?,?small character group 4?,?small character group 5 ?, among which, the marking method of group 2 of small characters is to use lowercase letters and add the number 2 in the upper right corner. The labeling methods for other groups can be deduced in the same way. 3 Q$ Group?, ?2 groups of large characters? The sounds of the small character group are marked with lowercase letters without numerical superscripts, such as c, d, e, f, g, a, b;

2 The sounds of the large character group Use capital letters without numerical subscripts to mark them, such as C, D, E, F, G, A, B; 3 v7 q# k4 p6 E# G/ I

? 1 group of large characters? and? The sounds of the 2 groups of large characters are represented by capital letters and numerical subscripts at the lower right: such as F1, G1, B2, A2? ' n8 d# z uamp; g V5 ^: d0 m6 X

Let’s take the piano as an example to introduce the grouping of children’s tones (only the groups of basic tone levels are listed)? On the piano, from left to right (from low to high )The grouping of basic tone levels (white keys) is: b Y" J- W8 Q* oamp; p) I: n

Staff notation uses many parallel horizontal lines, notes, and rests to record music. Notes and rests of different shapes indicate the duration of each note (the duration of the sound), and the position of these notes on the staff determines the pitch of the sound. 1. Music score composition

The basic music score has five parallel horizontal lines. The empty part between two adjacent lines is called "space". The staff music score uses these lines and spaces to record music. of. On the staff, the five lines and the four spaces are calculated from bottom to top, that is, the bottom line is called the first line, and the one above it is called the second line. The rest are calculated in this way, all the way to the fifth line; from the fifth line The rooms drawn between the first line and the second line are called the first room, and those above are called the second room, the third room, and the fourth room. ( C( `2 N( f： a0 R) Y

Obviously, if we only use the five lines and four spaces on the basic spectrum, we can only record 9 basic note levels at most, plus The upper level change is only 14 notes, which is far from enough in many musical works.

Therefore, in order to record the pitch level that is higher than the first line or lower than the fifth line, many short lines must be added above the fifth line or below the first line, called "plus lines". The addition lines located above the basic music chart are called upper addition lines, and those below are called lower addition lines, and thus the upper addition lines and the lower addition lines are produced. $ u7 t b, U6 a7 p

The calculation method of the added line and the added space is: the calculation method of the upper added line and the upper added space is the same as that of the basic music chart, and is also calculated from bottom to top. That is: the additional lines above the fifth line are: add one line above, add two lines above, and add three lines above?. The space formed by the fifth line and the upper plus line is called the upper plus line, and so on upward; the space between the lower plus line and the lower plus line is calculated from top to bottom. That is: the additional lines below the first line are: add one line below, add two lines below, and add three lines below?. The room formed by the first line and the lower line is called the lower plus one room, and the order downward is, the lower plus two rooms, the lower plus three rooms, the lower plus four rooms?. / \* l" a5 ]/ ~ 2. Notes and rests:

Notes are symbols that record the duration (duration) of sounds on the staff.

Rests are symbols that record sounds. The symbol of the duration of the pause. Rests also record sounds, but the sounds they record do not sound. It can be said that rests are "silent notes", which are also of great significance to the performance of music.

1. What is music:

What are the three elements of sound? They are sound quality/timbre/volume. Needless to say, the volume is too small for people to hear clearly, and too loud for the human body. Instinctively, there will be physical discomfort, so what does the quality of the sound depend on? It is the sound quality! The quality of the sound is the basis for determining whether the sound sounds good. This is why it is said that a good piano is the key. Only if you have a good piano Only when you play the piano can you truly understand what the so-called good sound is like. The quality of the timbre is based on the sound quality, so for players (especially bass), good sound quality should be the first pursuit. When it comes to sound quality, you will find that good sound is almost at your fingertips, and it is countless times easier to pursue good sound than a piano with poor sound quality.

2. What is a scale:
